I sweat a lot at night its so excessive, its worrying me. i have started to keep a towel with me every night to wipe off the sweat ?

Night sweats: Night sweats -- enough to wet the sheets -- usually are a sign of fever, often due to a systemic infection like tuberculosis, although almost any infection can do it. Take your temperature 3-4 times a day and record the results. If sometimes elevated (over 100F or 38C), see a doctor right away. Even if not elevated, see a doctor if the problem continues more than 1-2 weeks. Good luck.
